SDS-max® Rotary Hammer Bits
Bosch carbide rotary hammer bits feature tips that
stay sharper longer and deliver more holes within
their ANSI specification than competitors’ bits. Also,
Bosch shafts wear at a much slower rate than most
others and can take more abuse because of Bosch’s
technologically advanced conditioning process.
• Manufactured to ANSI standards, Bosch bits also meet and exceed ISO
(International Standards Organization) standards. 98% of the carbide tips
are molded to the specific ANSI size. Only 2% (specials) of all bit diameters
are ground to size
• SDS-max® rotary hammer bits not only fit Bosch SDS-max® hammers, but
also competitive SDS-max® drive hammers and Hilti hammers using TE-Y
and TE-FY shanks

Thru-Hole Bit Features
• Ideal for horizontal drilling applications
• Drill all the way through material without stopping
Bosch thru-hole bits are one-piece bits designed
for fast working without the need to change shanks.
The all-in-one core with SDS-max® or Spline shank
transmits power directly to the end of the bit. In
addition, thru-hole bits are economical due to their
long life (dimensions are nominal).
